PROCEDURE
实验过程
A mixture of [5-fluoro-7-(methylsulfonyl)-2,3-dihydro-1,4-benzodioxin-2-yl]methyl 4-methylbenzenesulfonate (0.4 g, 1 mmol), methanamine (1 ml, 40% in water) and ACN (3 ml) was heated under microwave radiation at 120° C. for 20 min. Purification on flash column chromatography (EtOAc/MeOH) gave the title compound. Yield: 0.2 g, 69%. The amine was converted to the hydrochloric acid salt and crystallized from EtOH/Et2O. M.p. 243° C. MS m/z (rel. intensity, 70 eV) 275 (M+, 81), 97 (48), 70 (bp), 69 (73), 63 (58).
